The Saskatchewan Roughriders announced Wednesday they had signed two former NFL draft picks and released a third.

The CFL team announced the signings of import defensive end Jammie Kirlew and import defensive back Chip Vaughn. As well, import defensive end Chris Ellis was released.

Kirlew, a 6-foot-1, 260-pound product of Tarrytown, N.Y., was drafted by the Denver Broncos in the seventh round (232nd overall) of the 2010 draft out of Indiana University.

He attended the Broncos' training camp and appeared in one pre-season game, but was subsequently released. He then joined the Buffalo Bills and spent the rest of that season on their practice squad.

In 2011, Kirlew played in one regular-season game with the Jacksonville Jaguars before being put on their practice squad. He was waived by the Jaguars in April of 2012.

Vaughn was a fourth-round selection (116th overall) of the New Orleans Saints in the 2009 NFL draft, but the Wake Forest University product spent that season on injured reserve.

The 6-foot-2, 221-pounder had a stint on the Philadelphia Eagles' practice squad in 2010 before joining the Indianapolis Colts, with whom he played three regular-season games that season. Vaughn was waived by the Colts in August of 2011.

Ellis, a third-round pick of the Bills in the 2008 draft out of Virginia Tech University, signed with the Roughriders in March.

He appeared in two regular-season games last season, but didn't register any statistics. He spent the majority of the season on Saskatchewan's injured lists.
